94 explorer 4.0 pushrod engine
For some time, the engine has had a rough idle issue starting warm, and the other day it died going down the road.
Now it's rough idle COLD AND WARM and lack of power going down the road ONLY WHEN WARM. It's fine driving cold, but when it warms up, it's like hitting a wall and it bogs down and I can't go any faster than 35mph.
I'm stumped. What I have done:
No CEL, it flashed on for 5 seconds going down the road and went back out again...
Anyone got ideas? Cleaning the MAF next...

I'm stumped. What I have done:
- Egr valve replaced
- Egr tube replaced
- DPFE sensor replaced
- Spark plugs replaced
- Plug wires replaced
- Ignition coil replaced
- Checked the cats (clean)
- Fuel filter replaced
- Fuel pump replaced
- Checked fuel pressure (30psi idle)
